Investigation of the cyclic nature of severe hydrometeorological events

The synchronization of severe hydrometeorological events with the maxima-maximora of the tidal forces of the Moon and the Sun is checked. The cycles of lunar and solar eclipses ‒ Saros and Exeligmos – are used as indicators of the latter. Flood levels on the Ural, Tobol, Ishim, Vagai, and Oka rivers in 2024 and 1970 are compared. It is shown that the catastrophic flood levels in 2024 were preceded by record flood levels in 1970. Severe droughts in the Volga region in 1921 and 1975 and abnormal frosts in Moscow in 1924 and 1978 are associated with the same Exeligmos cycle.
